Problems solved by technology

However, since the organometallic catalyst usually used as a gel catalyst is very easy to hydrolyze, the catalytic performance will drop sharply in about a week in the all-water foaming system until it does not solidify, and it is difficult to store for a long time. Sensitive catalyst, although it can solve the problem of catalyst hydrolysis, but because the temperature-sensitive catalyst has very strict requirements on the reaction temperature, the catalytic performance is very low at room temperature, and the catalytic performance will increase several times to dozens of times after heating, so it is difficult to be used as a cold curing catalyst. The use of polyurethane catalysts, the products made of them are limited in construction sites without heating conditions

Abstract

The invention relates to an all-water foaming cold-cure foam fireproof sealant and a preparation method thereof and belongs to the technical field of fireproof sealing materials. The all-water foaming cold-cure foam fireproof sealant is prepared from 100 parts of polylol, 38-50 parts of a liquid-state phosphate fire retardant, 110-120 parts of a powdered fire retardant, 2-5 parts of pigments, 1.8-4 parts of de-ionized water, 0.5-1.8 parts of a tertiary amine catalyst, 1.8-2.4 parts of an anti-hydrolysis temperature-sensitive catalyst, 1.8-2.5 parts of a chain extender, 0.4-0.6 part of high-activity silicone oil, 2.76-11 parts of a catalytic activation agent, 0.8-1.8 parts of a coupling agent and 64-169 parts of polyisocyanate. The all-water foaming cold-cure foam fireproof sealant has the beneficial effects that the substrate attaching force is more excellent, the light weight can be guaranteed, and the requirements on environment protection can also be met; a quaternary ammonium salt temperature-sensitive catalyst is used as an anti-hydrolysis gel catalyst and meets the field utilization requirements without heating conditions; and a formed foaming layer not only has excellent fire resistance, but also can be expanded to form a firm and dense carbon layer after a fire disaster occurs, so as to prevent flame from spreading and prevent heat propagation.

Description

technical field [0001] The invention relates to the technical field of fireproof sealing materials, in particular to an all-water-foamed cold-cured foam fireproof caulking glue and a preparation method thereof. Background technique [0002] Fireproof caulking glue is mainly used for fireproof separation of through holes formed when cables, bridges, tank boxes, air ducts, material conveying pipes, etc. pass through walls and floors. Compared with traditional fireproof sealing materials such as fireproof plaster, fireproof mud and fireproof bag, it has the advantages of convenient construction, long service life, good weather resistance, earthquake resistance and crack resistance, good adhesion to most substrates, and no corrosion of cables. . [0003] The fireproof caulking adhesives on the market mainly use silicone systems or water-based acrylic systems, which have disadvantages such as long curing time, poor mildew resistance, and poor adhesion to certain substrates. Alt...
